CALCULATING-MACHINE.

Specification of Letters atent.

Application filed February 20, 19.1.4. Serial No. 819,978.

My invention relates to'improvements in calculating machines, and more particularly in calculating machines in which the setting mechanism consists of disks provided with .radially shiftable teeth representing the values to be transmitted to the registering mechanism, and cam disks coperating with the disks and adapted to shift the desired number of teeth .into operative positions. In machines ofthis class the registering mechanism is'mounted on a laterally shiftable carriage, which also carries a revolutions counting mechanism, the revolutions counting mechanism being ordinarily mounted at the left hand side of the register-ing mechanism. A machine of this class is shown for example in the patent of the United States No. 1,040,059, vdated October 1, 1912, granted vto Franz Trinks.

In calculating machines which are .designed for performing calculations of every kind the revolutions counting mechanism must be constructed in such a way, that it can be used in a similar way as the registering mechanism, and more particularly it must be possible to operate the numeral wheels of any order. For this reason between adjacent numeral wheels of the revolutions counting mechanism sets of gear wheels have been provided for the carrying opei'a."'on which can be rocked in radial direction. rThese sets of gear wheels can be rocked independently of each jother, and they are rocked by the operating mechanism for the carrying mechanism, which travels on the carriage from one numeral wheel to the other and is operated Yin such a way, that during the revolution of the crank and prior to the operation of a numeral wheel of the revolutions counting mechanism the carrying mechanism which is located at the right. of the said. numeral wheel is thrown out of operation. Mechanism of this kind is shown for example in the patent of the United States No. 1,007,618, dated October 31, 1911, granted to Franz Trinks. This mechanism requires much space and it is very heavy, and furthermore the heads of the teeth of the sets ofgear wheels are liable to engaget-heheads of the spur gears connected with the numeral wheels when 'the sets of gear wheels are rocked backward.

The object of the improvements is to provide a mechanism of this kind, in whichithe numeral wheel which is located in each case at the right of the driving mechanism is thrown out of operation by axially displacing the coperating intermediate gear Wheel. By 'tlnis constructing the mechanism the carrying mechanism is thrown out of opera-A tion in, a reliable way, because the mechanism provided therefore is mounted on the same axis as the intermediate gear wheels, and the intermediate gear wheels are thrown into operation by the moving tooth controlling the same, before advancing the same.

For the purpose of explaining the invention an example embodying` the same has been shown in the accompanying drawings, in which the same letters of reference have heen used in all the views to indicate corresponding parts.

Insaid drawings-Figure 1, is a front view of the calculating machine partly in section and with the cover of the casing partly reli'ioved and showing the carriage in the normal position. Fig. 2, is a cross-section of the machine taken on the line 2-2 of Fig. l, and Fig. 3, is a front View similar to that shown in Fig. 1 and'illustrating a pai-tof the revolutions counting mechanism the carriage of which has been shifted a dirtance corresponding to one order.

In the example shown in the drawings a Patented June 16, 1914.

calculating machine has been shown 1nl which the revolutions counting mechanismis located at theleft of the registering mechanism and on'a carriage which is shiftable in a direction parallel to the axis of the setting disks, the revolutions counting mechanism being shiftable relatively to a nonshiftable single tooth" provided for operat-l ing the same.

The setting mechanism consists of setadapted to be rotated from av crank c3 by means of gear wheels c1 and c2. The setting tino' disks which'are mounted on a shaft c disks are provided with radially shiftable teeth which are adapted to he shifted in radial direction by means of cam disks projecting with handles e through slits jl made L in the cover. of the casing. Then rotating J ing mechanism.

' Each of the numeral disks a of the revolutions counting mechanism is provided'a-t its right hand face with a gear Wheel provided 'with ten teeth. At the lett hand face each of the said disks is provided with s ilange b formed with a single tooth t, All the disks are loosely mounted together with their gearings on a shaft d which is also used for resetting the revolutions counting mechanism and is providedior this 'purpose with Wing nut al', as is shownvin Fig. l.

0n the ca riage Q a shaft g is iiXed on which intermediate gear Wheels 7i are loosely mountedywhich .are in mesh with the gear Wheels and at the right of each of the intermediate gear wheels it levers are supported which are adapted to be rocked on the said axis at a certain angle. The hubs oi the levers are formed with notches z" the side Walls of which are beveled to opposite sides. The said notches are engaged by noses 1 of disks 7s which are formed accordingly. The disks are provided at both sides of the levers z' with arms lo and they are rigidly secured to the stationary aXis g. The arms le project into the plane through which the levers i are moved, and they limit the rocking movements of the latter in both directions.A

Between each ci the disks .7c and the adjacent intermediate gear Wheel 7L there is a spring j which has the tendency to force the cooperatingintermediate gear 'Wheel la' and the huh of the adjacent rocking lever i against theA disk and with the nose it in engagement with the cooperating notch ef.

In therelative position of the parts c and shown in the drawings the lever a' is in the middle between the stop arms le, as is shown in Fig. 2. The breadth of the intermediate gear Wheel it is such, that its teeth are disposed in the plane of the gear Wheel aswell as in that 'of the single tooth My invention 'relates of the numeral disk c'. of the next lower fv, '012. The gear Wheel 7 is connected with a lever c providing a single tooth, which carries an are shaped member o directed from the single tooth to oppo disposed in the plane of the lever li the carriage g is in the normal position shown in Fig. l, and the crank c is turned, the single tooth o engages the lirst one of the .intermedia-te gear Wheels-7L which is located in Fig. l at the right hand end of the revolutions counting mech anism. Thereby the revolutions counting mechanism is advanced a distance corresponding to one value, as is known in the if the ear- .lte sides and i.

ria `e is shifted to the right `for oxam'olo the dista-nce ci? two adjacent numeral Wheels and into the position shown in Fig, which the single tooth 0 cooperates with numeral Wheel of a higher order, and if noay the crank of the machine is turned, at first the corresponding end of the arc shaped member o enga-ges the lever z' which is l0- cated in the path of the said member, and rocks the same so far that the notch t rises on the beveled nose le of the disk-lc. `Thereby the coperating intermediate gear wheel 7L is shifted to the left and out of the plane of the tooth t', so that it is in engagement only with the gear Wheel Therefore the single tooth o has no effect on the disks c of the revolutions counting mechanism which are located at the right thereof, and as it passes the intermediate gear Wheel, only the disk which is located at the left is advanced.

The advancing movement is transmitted to theV left hand part of the revolutions counting mechanism, because the intermediate gear wheels are in such positions, that they are in the paths of the single teeth t as Well as inthe plane of the gear Wheels b of the next following numeral Wheel.

The length of the arc shaped member 0 and the relative distance of the stationary stops 7c are such that when rocking the lever z' the notches are not perfectly discri- .gaged from the noses 7ca so that after the tooth o haswbeen disengaged fromwthe cooperating intermediate gear Wheel. /t the lever is returned bythe spring f into initial position in which it istat the middle between the stops le.

In order that With the same direction of rotation of the main lvshaft a whichucarrics the setting disks and the'shiftable lteeth the tooth o can he rotated either to the right loc or to the left, a gear Wheel p is provided on the shaft n, which is longitudinally 'shiftable thereon and is adapted to be rotated from the main shaft by the intermediate gear Wheelsii, o1, e2, and the -said gear wheel is in engagement according to its position either With the broad spur gearing 1a mounted on the sha-ft m or with the reversing gearings s. The latter has likewise a considerable breadth and is always in mesh with the spur gearing r. If the gear wheel p is shifted by means of a sliding rod t from the position shown in Fig. l to the lett and ing in one direction. 'If the gear Wheel p is shifted relatively to the gear wheel s, the latter transmits the rotation to the single tooth 0.

By reason of this construction the direction of rotation can at any time be reversed Without interfering With l,the proper function of themechanism.
